“开关电池”其实是给电池按个开关，不让电池内的电能缓慢的流失，当要使用电池时，只要将开关推上正极出头即可使用，思路非常的好，但是会增加不少的制造成本。设计师：Ren Tong & Luo Jie。

Switch Battery
This "Switch Battery" is in fact mounted with a switch that prevents the internal electrical energy from draining away slowly. To use the battery, just push the switch to the positive end. It is an excellent train of thought, but will add a lot to the cost of manufacture. Designer: Ren Tong & Luo Jie
